I have exactly the similar configuration, except for G.Skill 4GB DDR RAM and FSP SAGA II 500W SMPS.
I do remember the AMD driver crash on my system, I think 3 times it crashed, but thats all.. I think after I updated the drivers to 11.10 it stopped crashing.
BTW can you give us the Exact RAM Model which you are using, AFAIK and as reported by other members of this forum some Corsair models have issues with Sandy Bridge.
I am quoting this reply from Cilus from one of my threads.
DOn't get XMS3 for Sandy Bridge motherboards as Sandy Bridge Mobo ram slots are operate on 1.5V whereas XMS3 is a 1.65V ram module. I've heard about some incompatibility issues between these high voltage ram modules and Sandy Bridge mobos.
As you have already given your GPU for RMA, you can research if there is any problem with the RAM you are using.
EDIT: your temperature is also normal, mine hit 69°-71° C
